The study focused on the performance evaluation of near-reference monitors, specifically the cutting-edge Sapiens MASAF300 sensors. These sensors were strategically placed alongside reference stations in Milan, Italy, serving as representative multiparametric reference stations.

The results were nothing short of remarkable. The near-reference monitors demonstrated exceptional correlation with the reference monitors across all pollutants analyzed. Its compact design also enables convenient deployment and autonomous remote operation.

By harnessing the power of near-reference monitors, AMAT can now effectively determine the nature of traffic emissions at multiple near-roadway community sites and evaluate the effectiveness of Milan's traffic management plans and policies. Urban authorities could also make informed decisions to implement impactful air quality policies.
